Trait Implementations

impl<Fut, E> Future for ErrInto<Fut, E> where
    Fut: TryFuture,
    <Fut as TryFuture>::Error: Into<E>, 

type Output = Result<<Fut as TryFuture>::Ok, E>

The type of value produced on completion.

fn poll(
    self: Pin<&mut ErrInto<Fut, E>>,
    cx: &mut Context
) -> Poll<<ErrInto<Fut, E> as Future>::Output>

Attempt to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.

impl<Fut, E> Unpin for ErrInto<Fut, E> where
    Fut: Unpin, 

impl<Fut, E> Debug for ErrInto<Fut, E> where
    E: Debug,
    Fut: Debug, 

fn fmt(&self, f: &mut Formatter) -> Result<(), Error>

Formats the value using the given formatter.

impl<Fut, E> FusedFuture for ErrInto<Fut, E> where
    Fut: TryFuture + FusedFuture,
    <Fut as TryFuture>::Error: Into<E>, 

fn is_terminated(&self) -> bool

Returns true if the underlying future should no longer be polled.
